Heng Qi f61fe5f081 virtio-net: fix the vq coalescing setting for vq resize 
According to the definition of virtqueue coalescing spec[1]:

  Upon disabling and re-enabling a transmit virtqueue, the device MUST set
  the coalescing parameters of the virtqueue to those configured through the
  VIRTIO_NET_CTRL_NOTF_COAL_TX_SET command, or, if the driver did not set
  any TX coalescing parameters, to 0.

  Upon disabling and re-enabling a receive virtqueue, the device MUST set
  the coalescing parameters of the virtqueue to those configured through the
  VIRTIO_NET_CTRL_NOTF_COAL_RX_SET command, or, if the driver did not set
  any RX coalescing parameters, to 0.

We need to add this setting for vq resize (ethtool -G) where vq_reset happens.

README 

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
